Respuesta:
60°
Explicación:
Paso 1: Información dada
- Distancia recorrida (d): 2000 cm
- Fuerza aplicada (F): 80 N
- Trabajo realizado (W): 800 J
Paso 2: Convertir "d" a metros
Usaremos el factor de conversión 1 m = 100 cm.
2000 cm × 1 m/100 cm = 20 m
Paso 3: Calcular el ángulo entre la cuerda y el suelo (θ)
W = F × d × cosθ
800 J = 80 N × 20 m × cosθ
θ = 60°
Answer:
the relationship between fleas and a dog is a parasitic relationship.
Nucleosomes are the basic packing unit of DNA built from histone proteins around which DNA is coiled. They serve as a scaffold for formation of higher order chromatin structure as well as for a layer of regulatory control of gene expression.
Answer:
c. alkyne.
Explanation:
Hello there!
In this case, according to the attached file, it turns out possible for us to say that alkanes have only single-bonded carbon atoms, alkenes have two double-bonded carbon atoms and alkynes have two triple-bonded carbon atoms.
In such a way, according to the aforementioned definition, we infer that that an organic compound that contains only carbon and hydrogen and a triple bond (all the other bonds are single bonds) is classified as c. alkyne.
Regards!
The answer is group 1A.
In the ionic compound formula X₂SO₄, SO₄ has a -2 charge. Hence to balance this -2 charge of SO₄, X must have a +1 charge.
Group 1A elements form X⁺ type of ions because they are metals. So, they have the tendency to lose electrons.
Hence, X must belong to the 1A group.
Ionic Compounds-
- Ionic compounds are formed by the electrostatic attraction between the anions and the cations.
- Cations are positively charged ions that are formed due to the loss of electrons.
- And the anions are negatively charged ions that are formed due to the gain of electrons.
- Due to this, they have opposite charges and form bonds known as Ionic Bond.
